Researchers at the University of Kentucky Center for Applied Energy Research and the Department of Chemistry have received a $1 million grant from the U.S. DOE to advance their innovative biofuels research.

 



The project is titled “Robust Engineered Catalysts for the Conversion of Waste Oleaginous Biomass Feedstocks to Fuel-like Hydrocarbons via Decarboxylation/Decarbonylation” and is funded by DOE’s Office of Energy Efficiency & Renewable Energy.

 



As part of the project, CAER will partner with Clariant Corp., Saola Energy and the National Renewable Energy Laboratory to develop a robust engineered decarboxylation/decarbonylation (deCOx) catalyst.

 



Successful development of such a catalyst is a critical step in the scale-up of novel deCOx technology to produce renewable fuels from waste-biomass feedstocks, or organic materials considered waste or byproducts.

 



“We believe this technology may provide an industrially viable alternative to the production of renewable diesel that can compete with—or even improve on the economics and greenhouse-gas reduction potential of—more commercially mature pathways,” said Eduardo Santillan-Jimenez, associate director of CAER’s Sustainable and Alternative Fuels group, adjunct assistant professor of chemistry in the College of Arts and Sciences and the project’s principal investigator.

 



In addition to developing an engineered catalyst, CAER researchers will test the latter in a continuous reactor as well as characterize the fresh, spent and regenerated catalyst to gain insights into its deactivation mechanism(s) and inform computational work.

 



To this end, CAER’s SAF group will collaborate with Chad Risko, a computational chemist in the UK College of Arts and Sciences’ Department of Chemistry who also conducts his research at the center.

 



“Leveraging the computational strengths of Dr. Risko’s laboratory is key to the successful development of an engineered catalyst,” said Santillan-Jimenez. “We take pride in being the catalysis experts in our lab, but our partnership with the Risko lab adds computational chemistry expertise that greatly expands our capabilities and impact.”

 



CAER’s SAF group has a long history of working with catalysts to give new life to waste-biomass feedstocks.

 



The group has pioneered a catalyst capable of transforming waste fats, oils and greases into liquid transportation fuels, including both renewable diesel and sustainable aviation fuel.

 



In this project, CAER will be utilizing brown grease, which is an abundant and inexpensive waste stream that is currently incinerated or landfilled, leading to greenhouse-gas emissions.

 



“No one wants brown grease,” said Robby Pace, a CAER researcher and co-investigator on the project. “But if we could take that waste stream and develop a novel way to put it to good use in the form of renewable diesel, that could have a positive impact on our environment and, hopefully, Kentucky’s economy.”

The educational experience at the University of Kentucky is truly remarkable. The professors are passionate and knowledgeable, making every class fun and informative. What sets this university apart from others is the manageable workload that allows students like me to combine their studies with other activities. In such a supportive environment, I become fully immersed in learning without the need for additional assistance from https://www.thesiswritingservice.com/uk-ghostwriting-services/. It's nice to know that here at the University of Kentucky I can succeed academically and achieve my goals on my own.
